Shock and blast waves mitigation

Modeling of particle cloud dispersion in compressible gas flows with shock waves

“…Other applications concern explosion in the confinement building, where the shock waves can be initiated accidentally. In order to mitigate their effects, an aqueous foam [12][13][14][15] or a water spray system 16 can be used. In this case, the shock-spray interaction can change dramatically the dispersion of droplets, leading to the change in the mitigation capacity of the spray system.…”

Development of mathematical model of localization of a small explosive object with the help of a specialized protective device

“…Questions of working with specialized protective devices for collective use are not considered. This is primarily due to the fact that today the greatest difficulties arise [5] when an explosive device is detected and neutralized. At the same time, the use of explosives throughout the world for carrying out terrorist acts revived interest both in the study of explosions and in the study of ways to prevent or mitigate damage from the use of explosives [6].…”

“…The analysis of such loads when passing through various geometric shapes is also carried out [10,11]. And, secondly, the study of mitigating mechanisms to minimize damage from impact and explosive load [5].…”

Blast mitigation effect of the foamed cement-base sacrificial cladding for tunnel structures

“…Tarlochan et al [7] conducted quasi-static compression experimental investigation of composite sandwich cladding structures fabricated from glass fiber, polystyrene foam and epoxy resin. Hadjadj and Sadot [8] described the mechanism of shock and blast wave mitigation in aqueous foam material. Britan et al [9] researched shock wave propagation through wet particulate foam material and gave the main parameters controlling the shock wave mitigation.…”
